Irreducible dorsal MTP joint dislocation in the second and third toes

Abstract

The strong plantar joint capsule consisting of the deep transverse metatarsal ligament and plantar plate, long and short flexor tendons, and lumbrical muscles are considered to be obstructions that interfere with the reduction of irreducible dorsal dislocation, independently or in combination with each other [2,3,5–7]. However, dorsal approaches were used previously in surgically treated cases of dorsal dislocation, and the excised deep transverse metatarsal ligament and plantar plate remained unsutured [3,5–7]. In our patient, the deep transverse metatarsal ligament in the plantar region independently interfered with the reduction of the dorsal MTP joint dislocation. Therefore, the use of a plantar approach during surgery was considered to be appropriate from the anatomical and physiological perspectives.
